Abstract □ 91

The brain stem was analysed and the presence of ubiquitin and neuron-specific enolase was detected in 7 cases of sudden infant death and in 12 cases of violent death. The presence of ubiquitin in neurons of 6 children dying suddenly (SID) confirmed other morphological changes connected with chronic hypoxia. In accidental deaths no such findings could be detected. Neuron-specific enolase was observed in mechanicaly damaged axons in 7 cases and no ubiquitin was present in the neurons of this group.
